is prtotype an object or a method?

I think it is a method but the book I am reading, a translation of morrison's book, said it is an object.

It is an object. You cannot invoke it. Methods are functions attached to an object. You can invoke them as such. Objects are just containers for data.

JavaScript's prototype object is an object that knows how to construct the object it belongs to. You can add new methods to a "class" by adding them to the prototype object for that class, among other interesting things. JavaScript's object model is a little quirky at first, but is actually very simple once you get used to it.

That's a constructor, prototype is just that - an object above your current object in the prototype chain.

so, are you saying a prototype is neither an object nor a method, but a constructor?

No, he's not saying that. The first sentence of this article describes it well:

http://en.wikipedia.org/wiki/Prototype- ... rogramming

The rest of the article should answer your questions.
